If it's oil (leaking outside) from the oil cooler, it's the inner set of O-rings. If it's coolant, than it's the outer set of o-rings. If either is mixing than it's the outer o-rings....not that it matters. i'd hope you would replace all of them
I just went thru this last weekend. I've heard people say "you may have to jack the motor." I could see any other way but to jack it up about 1".
Pretty messy, but well worth it! I hear they get $600 from the Stealership to R&R the oil cooler. I spent a whole $40 to do it myself...not including the new oil and coolant.
